Final answer:

The statements that describe the vectors that include points A(9,3), B(-3,6), and C(-7,-3) are: The magnitude of Vector AC is sqrt(2), the magnitude of Vector BC is sqrt(97), and the magnitude of Vector AB is 3*sqrt(17).

Step-by-step explanation:

To determine which statements describe the vectors that include points A(9,3), B(-3,6), and C(-7,-3), we can calculate the magnitudes and directions of each vector.

  1. Magnitude of Vector AC: We can use the distance formula to find the distance between points A and C, which is equal to sqrt((9-(-7))^2 + (3-(-3))^2). This is equal to sqrt(2).
  2. Magnitude of Vector BC: We can use the distance formula to find the distance between points B and C, which is equal to sqrt((-3-(-7))^2 + (6-(-3))^2). This is equal to sqrt(97).
  3. Magnitude of Vector AB: We can use the distance formula to find the distance between points A and B, which is equal to sqrt((9-(-3))^2 + (3-6)^2). This is equal to 3*sqrt(17).
  4. Vector AC: We can find the vector AC by subtracting the coordinates of point A from the coordinates of point C. This gives us AC = <-16, -6>.
  5. Vector BC: We can find the vector BC by subtracting the coordinates of point B from the coordinates of point C. This gives us BC = <10, 9>.
  6. Vector AB: We can find the vector AB by subtracting the coordinates of point A from the coordinates of point B. This gives us AB = <-12, 3>.
